Abstract
The invention discloses an illuminating wedge device of an anechoic chamber. The illuminating wedge device comprises a sound absorbing wedge and an illuminating lamp, and is characterized in that the sound absorbing wedge comprises a base part and a sharp part extending downwards from the base part; and the illuminating lamp is arranged in the sharp part. Therefore, the illuminating wedge device disclosed by the invention has the advantages that not only can the illumination be provided, but also the reflection to the sound can be reduced.
Description
Technical field
The present invention relates to a kind of illumination wedge device of anechoic chamber.
Background technology
Anechoic chamber, quiet room and silencer box (following is example with the anechoic chamber) are widely used in the acoustic measurement on the products such as machinery, electronics and Medical Devices, and it can be used as medical audiometry diagnosis room, language recording room, Shop floor control chamber or noise testing chamber.One of main effect of anechoic chamber is for forming the space of internal freedom sound field, and promptly house interior sound does not reflect, and therefore on metope, lays the sound-absorbing wedge, and it mainly act as the absorption sound wave, transfers acoustic energy to heat energy.Inside, anechoic chamber generally needs lighting installation, with convenient test, but general illuminating lamp, like electricity-saving lamp, its surface is irregularly shaped, and hard smooth, easily to the sound generating reflection, thereby causes anechoic chamber's internal freedom change of sound field.
Summary of the invention
The objective of the invention is to provides a kind of illumination wedge device of improved anechoic chamber to above-mentioned defective of the prior art, and it both can throw light on, and can reduce the reflection to sound again.
For realizing the foregoing invention purpose; The present invention has adopted following technical scheme: a kind of illumination wedge device of anechoic chamber; Comprise sound-absorbing wedge and illuminating lamp; It is characterized in that: said sound-absorbing wedge comprise base portion and from base portion to the tip that extends below, said illuminating lamp is installed on the inside of said tip.
In addition, the present invention also provides following attached technical scheme:
Said tip comprises medial surface, and said medial surface adopts smooth reflecting material.
Said smooth reflecting material is the mirror face stainless steel plate.
Said illuminating lamp is installed on the inner surface of said medial surface, and near said base portion.
Said medial surface also comprises strong damping material near the bottom of said base portion.
Than prior art; Advantage of the present invention is: the illumination wedge device of the anechoic chamber that is proposed; Through illuminating lamp being installed on the inside of sound-absorbing wedge; And smooth emissive material and strong damping material are adopted in the tip of sound-absorbing wedge, so both illumination can be provided, can reduce the reflection to sound again.
Description of drawings
Fig. 1 is corresponding to the illumination wedge device of the anechoic chamber of preferred embodiment of the present invention and to the schematic perspective view of light reflection.
Fig. 2 is the sketch map of the illumination wedge device of Fig. 1 to acoustic reflection.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof technical scheme of the present invention is done further nonrestrictive detailed description.
With reference to Fig. 1, a kind of illumination wedge device of anechoic chamber comprises sound-absorbing wedge 1 and illuminating lamp 4.Said sound-absorbing wedge 1 comprise base portion 3 and from base portion 3 to the tip that extends below 2.The quantity of said tip 2 is two and comprises medial surface 5 respectively.This medial surface 5 adopts smooth reflecting material to process, like the mirror face stainless steel plate.Said illuminating lamp 4 can be the LED lamp, and its quantity also is two, be installed on respectively on the inner surface of medial surface 5 of said tip 2, and near said base portion 3.After said illuminating lamp 4 was opened, because said medial surface 5 adopts smooth reflecting material, the light 8 that illuminating lamp 4 is sent passed through medial surface 5 continuous outwards reflection rays, thereby throws light on.
Further with reference to Fig. 2, said medial surface 5 also comprises strong damping material 7 near the bottom of said base portion 3.When external acoustic waves 9 got into this sound-absorbing wedge 1, according to principle of reflection, external acoustic waves 9 constantly reflected to the bottom near base portion 1 of tip 2 through medial surface 5, absorbed until the strong damping material 7 through medial surface 5, to reach the purpose that absorbs sound wave.
It is thus clear that; The illumination wedge device of anechoic chamber proposed by the invention, through illuminating lamp being installed on the inside of sound-absorbing wedge, and smooth emissive material and strong damping material are adopted in the tip of sound-absorbing wedge; So both illumination can be provided, can reduce reflection again to sound.
It is pointed out that above-mentioned preferred embodiment is merely explanation technical conceive of the present invention and characteristics, its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
Claims (5)
